You just need to deactivate the old license and activate it again using HWID of the new iPad.
You have 1 attempt of deactivation for commercial license in the Cabinet on the web-site (MY ACCOUNT section), but if you ran out of deactivation attempts please contact Support Team.

We can also reset your Site license, but you cannot do it in Cabinet yourself.

Activation means creation of the license file (.irl) with the help of the purchased activation key. After purchasing the license you receive the key which you will assign to the control panel (until the key is not assigned the control device is not defined).
This procedure is performed in the MY ACCOUNT section of the web site. All purchased keys should be added in the MY ACCOUNT section and then assigned to particular devices with the help of HWID/Serial Number.
The ready license file should be added in Transfer and uploaded to the control panel together with the visualization project. You can find more detailed information about the activation procedure here.

You cannot merge Site licenses. But you can do it with Device licenses. To merge two Device licenses for different drivers you should activate two license activation keys indicating the same HWID. Download the second activated license file on your PC. It will contain two drivers licensed with the help of two different keys.

No, there aren't.
The number of the controlled equipment is not limited and depends only on the project functional.

Only one Site license for one controller can be uploaded on one control panel with the one project.

But the Multi-design function iRidium enables upload of several projects on one control panel. For each of the project there is its Site license. The projects work independently but each of them can be activated from the current project by the command.

No, you can't. Buying a license for one of iRidium products you can control only the driver you indicated when purchasing the license (in this case - KNX). All other drivers cannot be controlled with the same license.

To receive the license which enables control both KNX and Modbus from one control panel you need to purchase activation keys for each of these products and activate them for one panel (using the same HWID). The license file created after activation of the second key will contain two supported drivers.
The second way is to purchase Full license which includes all iRidium drivers (besides HDL-BUS Pro).

Yes, you can. But there won't be any communication with equipment: you will not be able to send commands to controllers and receive feedback. The other functions (graphics, navigation, interface scripts) will work.

You don't need to update the licenses.
They are fully compatible. But in V2.1 identifiers of all iOS devices (iPhone, iPad, iPod touch) changed. It will affect upload of new projects on iOS panels. See more information here.

This error shows that you indicated the wrong unique panel identifier (HWID) or Serial Number of the controller you activate the license for.

Please see information about license activation and information about receiving identifiers one more time.

HWID is a unique device identifier. It should not change. Otherwise your license will not work. If you have such a problem there can be several explanations:

• you work on a virtual machine (Windows Emulator). Switch to the regular Windows based PC.
•  you have hard disk RAID-array used on your PC. Deactivate it.
